Changing between multiple Microsoft Teams accounts within the app or browser
Dear YJayH3,
Good day! Thank you for posting to Microsoft Community. We are happy to help you.
Based on your description, I understand that you have a query "Unable to switch to guest account".
It seems like you are experiencing some issues with switching between your guest account and personal/organization account on the Microsoft Teams app, as a guest user in Microsoft Teams, you may encounter some limitations when using the app or web version.
Regarding your first concern, it is possible that there may be a compatibility issue with the app on your device. I suggest checking if your app is up to date and if your device meets the minimum system requirements for the app.
For your second concern, it is normal, once you have switched to a personal or organization account, you will not be able to switch back to your guest account. This means that if you want to access your guest account, you will need to log out of your personal or organization account and then log back in as a guest.
Lastly, for your third concern, If you are signed in to your personal or organization account and then switch to your guest account, you will not be able to change your account back to your personal or organization account. This means that if you want to switch back to your personal or organization account, you will need to log out of your guest account and then log back in to your personal or organization account.
I hope the above information will be helpful. Please feel free to let me know if there are any updates or if I've got you wrong. Glad to assist you. We sincerely appreciate your patience and cooperation. Thanks for your precious time!
Sincerely,
De Paul| Microsoft Community Moderator
